Be it known that I, PHILLIP F. POORBAUGH, a citizen of the United Statesof America, re= siding at Allegheny, in the' county of Allegheny andState of Pennsylvania hav'e in vented certain new and usefulImprovements in Steel-Oar Construction, of which the following is aspecification,- reference beinghad therein to the accompanying drawings.

My invention relates to certainnew and useful improvements in steel-carconstruction, and more particularly to that class known as pit-cars.

One of the objects of my invention is to lessen the weight of materialused in the construction of cars of this kind, as Well as in,- creasethe durability of the same, lessening the length of the car withoutdecreasing its carrying capacity, and thereby overcoming suchobjectionable features heretofore in the wooden and heavy steel pit-carsnow in use.

A further object of my invention lies in my improved hollow axle used inthe construction of the car and adapted to receive a stub upon which thewheel is mounted, the stub being shrunk into the end of. the axle,securely holding the same in position. By this arrangement the followingadvantages are obtained: The axle will wear better. It will be lighterand stronger, andits use in the mannerset forth materially lessens theweight of the car, and also by the use of the stub the same when worncan be easily replaced within the axle without entirely or partlydestroying the same.

A further object of my'invention lies in my improved end-gate or doorused in the construction of the car and which is so arranged as to belifted from the end of the'car when the same is tilted and when solifted being entirely out of the way of the moving coal. This preventsthe pounding or breaking of the end-gate to'pieces, as is usually thecase in pit-cars now in use. Furthermore, I provide the car with meansfor securely locking the end-gate or door thereto when the car is nottilted, the importance of which can be very readily seen, particularlyin the use of such cars for shaft-mines.

A further object of my invention lies in constructing a car with adraw-bar on the underneath face of the bottom, the movement thereof notbeing hampered by the coal re'stf ing upon the same, obtaining by suchconstruction a decreased draft when a train of cars are rounding'acurve.

Afurther object of myinvention lies in constructinga car in such amanner as to bring thebody thereof closer to the rails and at the sametime provide a car with supportingwheels of larger diameter and aheavier flange. This is obtained by a bearing-sleeve for the axlearranged in the manner herein described.

My invention consists in the novel construc tion, combination, andarrangement of parts to be hereinafter more fully described, andspecifically pointed out in the claims.

In describing the invention in detail reference is had to theaccompanying drawings,- forming a part of this specificatiomand Where'in like numerals of reference indicate corresponding parts throughoutthesev'eral views, in which- Figure .l is a perspective viewof myimproved car when set up. i Fig. 2 is a crosssectional view thereof,partly broken away,

through one of the axles. Fig. 3 is an end view, partlybroken away, thewheel being in section, showing the hub of the same of a greaterdiameter to receive roller-bearings when mounted on the stub. Fig. 4 isa vertical sectional View, the wheel partly broken away, showing thearrangement of the rollerbearings and a self-oiling means. Fig.6 is aside view of the bearing-sleeve. Fig'. 6 is a' perspective view of thedrawbar partly broken away.

. Referring to the drawings by referencenum'erals, 1 indicates thebottom of the car, which is substantially rectangular and upon which ismounted a vertical section 2, forming the lower part of the sides.Mounted upon the sections 2 is the intermediate section 3 of the sides,these intermediate sections flaring outwardly or arranged at aninclination, as shown, and are adapted to support the top verticalsection 4.

Y 5 indicates the front end of the car and is arranged between thesides, as shown, and supported on the bottom. This front end isconstructed of a shape formed by the lower two and intermediate flaringor inclined section 3, so that the end 5 will fit neatly between thesides formed by the sections. The

and top are formed of suitable also secured togetherby the T brace-irons7 8, the brace 7 arranged centrally of the outer face of the car and thebrace ,8 at the rear end of the sides. These brace-irons, as well asthebrace-iron 6, are securedto the car by any desirablefastening means. 9indicates my improved end-gate or door for the car and is of such shapeas formed 1 by the rear edges of the sections forming the sides andrests at its lower end upon the bottom 1, which projects for thatpurpose. The end-gate or door 9 is provided with a pair of strengtheningstuds or braces 10 11, suitably secured to the outer face thereof andhaving ismounted the wheel 29 and or end-gate 9.

arranged between the same a hook-rod '12, the upperend thereof beingformed in a curvilinear mannerand projecting above the door The lowerportion of the outer face of the end-gate or door 9 has suitably securedthereto a transversely-extending fasten-ing-bar13, projecting outwardlyon each side thereof, and which is adapted to engage the -Lshapedirons14, one of which is secured-to the lower rear corner of the sections 2and projects slightly therefrom, so thatthe upwardly-extending end ofthe iron 14 will form a means for retaining the end-gate or door in aclosed position-that is, against the rear end of the car. The end-gateor door 9 is pivotallyconnected to the sides of the car by means of thehanger-rods 15 16, one edge of which is bent at an angle and secured tothe end-gate or door, as at 17, and the oppositev end pivotallyconnected, as at'18, to the keeper 19, secured to each side of thesection 3 of- .the sides. V indicates an angle-iron secured to thebottom 1, as shown, and supports a draw-bar 21,:which is suitablysecured therein, as well as; supporting the projecting irons 22 forbuffers 23- 24. The draw-bar 21 is formedin three sections, the centralsection being secured to the bottom of the car and the end sectionsswivel] y connected to the central secfi OD My improved axles 25 for thecar are con structed in a hollow manner, as shown, and arranged incloserelation to the underneath face of the bottom 1. Each end of the axles25 is supported in a bearing-sleeve 26, secured to each side of theunderneath face of the bottom, as at 27.

28 indicates a solid-metal stub upon which retained in position: thereonby means of a washer 30 and cotter-pin -31. The stub 28 is of aslightlygreater diameter th an the opening in the axle- 25 and is shrunkwithin the samefor the pur pose of securely holding the stub inposition. Toprevent a lateral movement of the stub and axle in eitherdirection, I provide the openingin the bearing-sleeve of two differentdiameters, formingan offset or shoulder 32, against which the ends ofthe hollow axle abut, so that when the same is in position it is fixed.In case it is desirable to use'rollerthe wheel is made of a greaterdiameter than the stub 28, so that the bearings can be placed betweenthe stub and hub, as will be seen in Fig. 4. These bearings are retainedin position by means of the washer 31 on one side and the outer face ofthe bearing-sleeve 26 on the opposite side.

age-chambers for the lubricant. v p

34 indicates a brake-rodcarrying a brakeshoe 35, which operates betweenthe wheels 29 and against the tread of the same, The rod 34 is pivotallysecured at one end'to the vided with a suitable handle 3 v 38 denotes asupporting-rack for the rod and permitsof the adjusting ofthe'brake-shoe in relation to the tread of the whee-l It is thought thatthe advantagesfroin the use of the'hollow axle and stub, together withmeans for preventing the lateral movement of the axle, can be readilyunderstood from the foregoing description. E

In operating the end-gate o-r door'ofthe car theend of the hook 12 isengaged by a suitable bar or rod. The car is then tilted. As the car istilting, the end-gate or door will be lifted free from the same in avertical manner until the coal is discharged therefrom and the carrighted'. I r

By forming thesidesof the carin: themanner shown the length of the carcan be lessened without decreasing its carrying capacity.

It is thought that the 'manyadvanta'g'es of my improved constructionrelativeto' cheap ness, durability, and strength can lie-readilyunderstood from the foregoingdescription, i taken in connection with theaccompanying drawings, and it will be notedthat various changes may bemade in the detailsof 'construction without departing from the generalspirit of my invention. I

Having thus fully describe'd myinvention, what I claim as new, and d'esire to secure by Letters Patent, is
